Improvement in machines for cutting cloth



UNITED STATES EPEEAIM B. WELLS, 0E NEW YORK, N. Y.

IMPROVEMENT IN MACHINES FOR CUTTING CLOTH.

I Specification forming part of Letters Patent No. 117 ,352, dated July25, 1871.

To all whom it may concern:

Be it known that I, EPHRAIM B. WELLS, of New York city, in the countyand State of New York, have invented a new and Improved Machine forCutting Cloth; and I do` hereby declare that the following is a full,clear, and exact description thereof, which will enable others skilledin the art to make and use the same, reference being had to theaccompanying drawing forming part of this specification.

Figure 1 represents a side elevation of my im! proved cloth-cuttingmachine. Fig. 2 is a vertical transverse section of the same. Fig. 3 isa horizontal section of the Same.

Similarletters of reference indicate correspond- I ing parts.

My invention consists in a new combination of instrumentalities to forma cloth-cuttin g machine, as hereinafter described and subsequentlypointed out in the claim.

A in the drawing represents the frame of my improved cutting-machine. BC are two drums mounted, respectively, upon horizontal shafts a and b,which han-g in horizontal frames c and d, pivoted to an upright post eof the main frame A. The drums B C are in line with each other, andserve to hold an endless band o r belt, D, which is made of thin metal,with projecting lancetshaped cutters ff that are sharpened at one orboth edges. The lower shaft b is, by a belt or gearing, connected withthe drivin g-shaft E, hung in A, to receive rotary motion therefrom.rIhe back ends of the frames c d are connected with each other by a rod,F, carrying a nut, y, and a spring or piece of rubber, h, under the nut.AVllhe nut and rod serve to hold-the band tense, and the spring gives itthe requisite degree of elasticity. From the post c projects an arm, i,carrying a grooved wheel, j, in which the band is guided, as shown, toprevent the swinging of the same. G is the platform on which the clothis supported. This platform is of circular form, as Shown in Fig. 3, andis surrounded by an annular platform, H, which is, by wheels k k,supported on a lower projecting flange, m, of the platform l G, so thatH can be turned aroimd G. Both platforms G and H are slotted to permitthe removal and application of the band.

The cloth to be cutis placed upon the platform G and fed against thecontinuous cutter in the requisite direction; it then arrives Yin rearof the cutter, where it will, in part, be supported Y by the ring H, andcan readily be brought in front of the cutter by turning the ring. Thisavoids, to a great extent, the labor of bodily carrying the cloth to thefront, such labor being, at times, considerable when the cloth in itsseveral thicknesses weighs one hundred pounds or more. Directly at thesides of the cutter are fastened to the platform G small metal plates 'll, which have a slight lateral play, being slotted where thefasteningpins pass through them. These plates line the slotaforementioned in the platform just in line with the cutter, and yieldslightly to the side whenever some cloth is dragged down into the Slotby the cutter. They therefore prevent the clogging of the machine.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- The pivoted frame c d, rod F, spring h, drums B C,endless band`cutter D f, adjustable guideplates l l, stationary table G,and movable table H, all combined, arranged, and operating as and forthe purpose described.
